Rick Porcello delivering for Tigers against Athletics. He has 24 scoreless innings over last three outings.

Porcello (11-4) had only one career complete game before blanking the Rangers on June 26, but now is the first Tigers pitcher since Jack Morris to throw back-to-back shutouts. Morris threw three in a row in July 1986.

Porcello is 3-0 with 24 scoreless innings over his last three outings. He also became the first pitcher since Baltimore's Jeff Ballard on Aug. 21, 1989, to throw a shutout without a walk or strikeout. No Detroit pitcher had done it since Dizzy Trout in 1944.

Mauer extended his hitting streak to 12 games with a two-run double in the fourth inning, but noticeably was limping as he ran to second base. The team said he has a strained muscle on his right side and will be evaluated today.

MARINERS 13, ASTROS 2 (at Houston) — Robinson Cano and Kyle Seager had three RBI apiece, James Jones added two and a seven-run sixth inning propelled Seattle to score a season high in a win.
